1 To all whom it may concern:

Be it known that we, WILLIAM and WILLIAM MORGAN, subjectsof the King ofGreat Britain, residing at Bridge street west,

Birmingham, in the county of Warwick, I England, and 45 Westbury road,Bristohin the county of Gloucester, England, respectively, have inventedcertain new and useful. Improvements in or Relatingto Fuses and the ilike [for Grenades, Projectiles, Land-Mines, andthe like, of which thefollowing is a specification.

This invention comprises certain improvements in or relatingto fuses andthe like for grenades, projectiles, land mines, and the l ke, and it hasfor its purpose to better protect Bi ckford type cord and like fusesfrom "atmospheric conditions and to reduce the possibility of mis-fireto a minimum. With this object in view the fuse end and the in- Iflammable part thereof, is waterproofed and the waterproofing isefiected in such a manner that the firing and combustion ofthe fuse isimproved. With this object in view we employ a waterproofing materialwhich is of a highly inflammable character.

In a convenient embodiment of the present invention, .we prepare asolution of I highly inflammable material, such as celluloid or.nitrated cellulose dissolved in a suitable solvent, such as ether andalcohol mixture for the lower nitrated compound, and

amylacetate for the more highly nitrated compounds. .The end of aBickford cord or like timefuse is coated with this solution by i anysuitable process, and the applied solujtionized area may be dusted orotherwise treated with gun powder. Afterward this gunpowder may ormaynot be treated with a second coating of the solution.

In order that this invention may be'clearly understood and readilycarried into practice, I. 45.

reference may be had to the appended explanatory drawing, whichillustrates in section, and on an enlarged scale a Bickford cord timefuse treated according to thepresent invention.

I a 18 the combustible fuse charge; bis the casing of the fuse, whichmay be of fabric or other appropriate material. To the end of r such afuse alayer or. coating 0 of highly inn flammable waterproofing materialis applied, said coating being extended overthe .Specification o fLetters Patent. Patentd Apr. 16, 1918. Application filed. December23,1915. Serial 1%. 138,540; 7 I i V sectional extremity of the casingb, as well as over the sectional extremity of thefuse charge a. Whenapplying this first coating,

a number of thefuses 00,12, may be located side by side and retained inclose contiguity with their extremities in a common plane,

. and the extremities may then be collectively treated with the coating0, as for instance by a brush or by spraying. The coated surfaces-maythen if desired be dusted or treated with meal or fine grain gun powder(:1,

fuse casing 22,- Or the entire fuse casing may if desired be coated withthe waterproofing solution. Eitherextremity or both extremities of thefuse may be treated ac cording tothe present invention.

. Alternatively the gun powder may be applied at the same timeas thesolution by making a paste of the gun powder and-the solution andsuitably treating the fuse with this paste. 7 b The solution may beutilized in a number of ways for waterproofing or protecting fromatmospheric conditions the fuse; for instance. in the manufacture of thefuse the combustible contents thereofmay be treated or impregnatedwiththe waterproofing solution. l

The invention is'applicable to fuses adapted to be fired by. apercussion cap or fuses adapted to be fired in any other applicablemanner. Ina fuse adapted, for instance, to be fired by virtue of theapplication of a suitable brimstone or like igniting firing portion atthe extremity adapted to be ignited byfriction, the brimstone orthe likemay be treated or impregnated with the waterproofing solution.
